  • Method for recovering volatile components from a solid
    Patent number: 9334172
    Abstract: In a method for recovering volatile components from a solid material, a liquid phase is mechanically removed from the solid material. Subsequently, the solid material is dried by exposing the solid material to superheated steam circulating in a closed circuit. From the closed circuit excess steam that contains volatile components given off by the solid material is removed. The volatile components are separated from the excess steam by condensing the excess steam to a condensed phase and the volatile components are from the condensed phase by adding suitable ions to the condensed phase to crystallize the volatile components.
    Type: Grant

  • Reactor for recovering phosphate salts from a liquid
    Publication number: 20130228457
    Abstract: The invention relates to a reactor (10) for completely separating phosphate from a liquid and for recovering phosphate salts, comprising a housing (12) and two electrodes having differing polarities, wherein a sacrificial anode (16) made of a magnesium-containing material and an inert cathode (18) are arranged concentrically inside the housing (12).
